Agnes Mary Clerke (10 February 1842 – 20 January 1907) was an astronomer and writer, mainly in the field of astronomy. She was born in Skibbereen, County Cork, Ireland, and died in London.
Agnes Clerke was the daughter of John William Clerke (ca. 1814–1890) who was, at the time, a bank manager in Skibbereen, and his wife Catherine Mary Deasy (b. ca. 1819) whose father was a judge's registrar. She had two siblings; her older sister, Ellen Mary, was born in 1840, and her younger brother, Aubrey St. John, was born in 1843. All of the Clerke children were entirely home schooled.
Following in her father's footsteps—while studying classics, he had also taken courses in astronomy—she developed an interest in astronomy from an early age, using her father's 4 inch telescope in her observations and had begun to write a history of astronomy at the age of 15. In 1861, aged 19, her family moved to Dublin, and in 1863 to Queenstown. At the age of 25, partly for health reasons together with her elder sister Ellen, she went to Italy where she stayed until 1877, chiefly at Florence, studying science, languages, and other subjects that would be useful in their later lives. In 1877 she settled in London.
Upon her return, she was able to get two articles, Brigandage in Sicily and Copernicus in Italy, written while she had been in Italy, published in the Edinburgh Review of October 1877. This led to her being asked by Adam and Charles Black, publishers of the Review, who also published the Encyclopaedia Britannica, to write biographies of a number of famous scientists for the ninth edition of the encyclopedia. This work let to a number of other commissions, including the publication of the article on Astronomy for the Catholic Encyclopedia. During her career she wrote reviews of many books, including some written in French, German, Greek, or Italian.
In 1885, she published her best known work A Popular History of Astronomy during the Nineteenth Century, which has received recognition beyond the time it was written.
Clerke was not a practical astronomer, instead collating, interpreting and summarising the results of astronomical research. In 1888 she spent three months at the Cape Observatory as the guest of the director, Sir David Gill, and his wife, and there became sufficiently familiar with spectroscopic work to be able to write about this newer branch of the science with increased clearness and confidence.
